Gaius is 19 and Amy is 4, which is apparently strange since she's supposed to only be a few years younger than Gaius. But they're both from a while in the future. Gaius won't be born for a good 5 or 6 years, I'm not really sure on the math." He stopped rambling to look up at Arthur, which he had been avoiding the entire time.
